中文摘要：

考察了重碳酸根离子（HCO3^-）、磷酸根离子（PO4^3-）、硫酸根离子（SO4^2-）和硝酸根离子（NO3^-）等自然水体中常见的无机阴离子对非均相催化臭氧氧化邻苯二甲酸（PA）的影响。结果表明,能够捕获羟基自由基（HO·）的HCO3--对羟基氧化铁催化臭氧氧化体系影响很大,会明显抑制该体系对PA的降解,而对氧化铈催化臭氧氧化体系基本没有影响。PO4^3-和SO4^2-对2个体系中PA的降解均有很大的抑制效果,而NO3--对此影响甚少。从这些无机阴离子的影响可以侧面证明羟基氧化铁催化臭氧氧化遵循羟基自由基机理,而氧化铈催化臭氧氧化PA主要依靠络合作用。

英文摘要：

Bicarbonate（ HCO3^-）,phosphate（ PO4^3-）,sulfate（ SO4^2-）,and nitrate（ NO3^-） as inorganic anions were selected to investigate the influence of inorganic anions on phthalic acid（ PA） degradation in the O3/CeO2 and O3/FeOOH systems. The results showed that HCO3^- had almost no inhibitory effect on the PA degradation in O3/CeO2,while it affected the degradation of PA in the O3/FeOOH system significantly. PO4^3- and SO4^2-,which have a strong chelating ability,curbed the removal of PA notably in the O3/CeO2 system. NO3^- influenced the systems slightly. It could be deduced that PA was mainly degraded by hydroxyl radical oxidation in the O3/FeOOH process,while complexation could be attributed to the PA degradation in the O3/CeO2 process.
